Lincoln and Guba (1985) explain that because interpretive research is based on a different set of ontological and epistemological assumptions than functionally-based research, the traditional notions of validity and reliability do not apply in the same fashion. They furnish an alternative set of criteria by which to judge the rigor of qualitative research. Credibility, Transfer ability, Depend ability, and Confirm ability. Each criterion includes a set of specific actions a researcher can take to help meet the criterion, as listed in Table II.
